Seefeld,Westlake, La., assignors to Pasco, Inc., Lake Charles, La., acorporation of Louisiana r 3 Filed Oct. 18, 1962, Ser.No. 231,464 8Claims. (Cl. 33-1845) This invention relates to a device for settingcopy, particularly for photographing, as in the case of the preparationof plates for use in offset printing, for example, but not limited tosuch specific use. In still greater particular, it relates to a holdingframework for characters, in which the latter are mounted by simpleplacement on a magnetic panel. Although devices of this general naturehave been propose-d heretofore, they have been attended with certainshortcomings, notably in respect to the efiiciency of the magneticfield, wherein individual magnets have been employed in schemes whereinthey are too large and too few in number to provide a finely Anotherdrawback in prior devices resides in the necessity for fixing thecharacters in place, for subsequent use or processing, after they havebeen tentativelyset by action of the magnetic elements.

It is therefore a general object of the present invention to provide adevice which isn ot subject to the aforesaid shortcomings, andparticularly to provide a device having a magnetic component ofminimized depth, and,

finely distributed field. An object related to the foregoing is toprovide a holder whichis adapted for mounting in conventional copyingcameras.

Yet another object is to provide a compact, magnetic component in atype-holding device, which includes a grid element for a guide inmounting the legends.

Another general object is to avoid the need for fixation of. charactersto the mount after initial setting.

More particularly, it is an object to provide a frame with side groovesor tracks, adaptedto receive. 21* sheetform magnetic component, and acooperating, calibrated scale, adapted for sliding movement along theframe, i overlying relation to the magnetic sheet.

These and other objects, which will be apparent, are

attained by the present invention, a preferred form of which isdescribed in the following specification, as illustrated in the drawing,in which:

FIGURE 1 is a top plan view of the frame, with the magnetic sheet andthe calibrated scale in place.

FIGURE 2 is a sectional view taken on the line 2-2 of FIGURE 1, and j V1 FIGURE 3 is a fragmentary view, in perspective, of one corner of themagnetic sheet, or board.

Referring to the drawing by characters of reference, there is shown abase frame comprising a planiform, rectangular latticework of aluminummaterial, including a pair of side rails 2, 4, an endrail 6, and crossrails 8 and 10. Medially of their width, rails 2 and 4 carry tracks 12,14, of inverted L form, defining a pair of mutually facing channels,providing slide tracks for 0pposite side edges of the magnetic plate orsheet 16 A section 13 of L stock similar to sections 12, 14, joins theends of the latter along one edge of the base plate 7 3,226,838 PatentedJan. 4, 1966 ice lation to rails 12, 14, so as to be slidabletherealong.

For facility in handling, placement and removal, the riders. 22, 24 haveupwardly extending tabs or plates 26, 28, respectively, and in order tobring the scale 20 into close proximity to the magnetic component 16,the scale distributed field which is equal to the demands of preissecured to the undersides of wedge-form tabs 30, 32,

extending inwardly from riders 22, 24, respectively.

As seen in FIGURE 3, the magnetic component 16 comprises a relativelythin sheet, or panel of plastic 34, with magnetic inserts 36, which isendowed with extra rigidity and durability by means of a base sheet 38,of stainless steel, the edges of which are folded around the edges ofplastic sheet 34, to provide retaining flanges or margins 40, whichserve, additionally as slide-bearing surfaces, for movement in tracks12, 14.

The magnetic board 16 will be fabricated in any suitable mannerconsistent with the materials employed in making up the aggregate. Forinstance, the metal particles, of suitable alloy for high-strengthmagnetic properties, such as Alnico, may be mixed with the raw plasticmaterial before molding or extruding, and thus become an integral partof the board, widely and uniformly dispersed, and. after shaping of theboard, it may be processed in a magnetic field, whereby each individualparticle becomes permanently magnetized, and the magnetic field throughthe board is the cumulative efiect of the totality of particles. Thus,the mounting board becomes a selfcontained, magnetic instrument, whichwill attract and hold characters of suitable ferric material, not onlyfor initial placement, but throughout an entire range of processing,including the taking of photographs.

The type, or other characters used, may be wholly of magneticallysusceptible material, such as the ferric metals, or may be of othermaterial, such as plastic, with a suitable layer or coating ofmagnetically susceptible material on its under side. I

For cooperative use with the guide scale 20, the top surface of magneticboard 34 carriesa cover sheet 42, of thin plastic material, suitablybonded, as by cement, and having a system of grid lines 44, shown asarranged in rectangular pattern, but which could also be arranged inother schemes. The grid lines 44 will preferably be of a color whichwill not photograph.

With the magnetic board 16 mounted in the base frame, the legend may bequickly, easily, and accurately laid out by simply placing thecharacters on top of the board, aided, if necessary, by the grid lines44 and the scale 2.0. With the legend laid out, the board 34 may bewithdrawn from the frame by sliding movement in tracks 22, 24, afterwhich it may be further used, or processed, at any location, and in anyposition of inclination or orientation, with the'legend remaining firmlyin place at all times. In particular, the thin board 34 is readilyadapted for insertion in the mounts of standard cameras. When the boardhas served its purpose for a given operation, the type, or characters,may be easily removed, by sidewise movement across the board, and theboard re-used for a fresh legend,

separately, or in conjunction with original copy. In all cases, theconventional, tedious and time-consuming process of pasting up of copy,required in all conventional processes, such as Foto Type, Artype,photographic headliners, and strip printers, is avoided.

While a certain, preferred embodiment has been shown and described,modifications will be apparent, in the light of this disclosure, and theinvention should not, therefore, be deemed as limited, except insofar asshall appear from the spirit and scope of the appended claims.
